Construction method for soil rock stratum tunnel to penetrate through pipeline leakage area
The invention belongs to the technical field of tunnel reinforcement, and relates to a construction method for a soil-rock stratum tunnel to pass through a pipeline leakage area, which comprises the following steps of: firstly, judging a pipeline leakage type of the soil-rock stratum tunnel to pass through the pipeline leakage area by taking a rock stratum thickness, a leakage area range and a tunnel hole diameter as parameters; a local resin normal-temperature curing lining method is adopted to repair a leakage pipeline, stratum grouting is adopted to reinforce a pipeline leakage area, upper half section grouting or advanced small pipe grouting is adopted to reinforce tunnel construction, field actual construction verification shows that the method can be applied to subway tunnel construction under the soil-rock composite stratum pipeline leakage condition, and the construction efficiency is improved. The popularization and application values are realized; according to the method, the underground pipeline leakage range is divided into four types, corresponding reinforcing means are adopted according to the influence of different leakage types on the stability in the tunnel excavation process, the reinforcing means comprise the two treatment measures of reinforcing a pipeline leakage area and reinforcing the pipeline leakage area and the tunnel construction range at the same time, and the stratum reinforcing quality is effectively improved.
